An API is a set of rules that lets one piece of software ask another for information or actions. For example, a weather app may use an API to request today’s forecast from a weather service, then display the result for you.

Use a reputable hosted authentication provider. For a two-person startup, authentication is security-critical but rarely differentiating, and building it well requires ongoing work across password storage, account recovery, MFA, session management, abuse prevention, compliance, monitoring, and incident response. A provider lets you launch faster and reduces the chance that a subtle implementation flaw compromises users. Choose one with standards-based integrations and an export path to limit lock-in. The strongest argument against this recommendation is vendor dependency: pricing can rise sharply with user growth, and migrating authentication later can be difficult because password hashes, MFA credentials, sessions, and identity links may not transfer cleanly.

Use an established hosted authentication provider. For a two-person startup, authentication is security-critical work that can consume time better spent building the product. Choose a provider with strong security features, transparent pricing, and a workable user export path. The strongest argument against this choice is dependence on a third party for access to your product: if the provider has an outage, your users may be unable to sign in, and you may have little control over how quickly the problem is fixed.

AI spending is hard to predict because usage, pricing, and implementation costs can all change quickly. Unlike traditional software, many AI services charge according to consumption: the number of questions asked, documents processed, images created, or computing resources used. A successful pilot can therefore become much more expensive when thousands of employees or customers adopt it. A second cause is uncertainty about which technology will be needed. Different AI models vary greatly in price, speed, and quality, while vendors frequently release new versions and revise commercial terms. Teams may also discover that a cheaper model is adequate for routine work but that sensitive or complex tasks require more costly systems. Third, the model itself is only part of the bill. Reliable AI often requires data preparation, system integration, security controls, testing, human review, monitoring, training, and legal or compliance work. These supporting costs are easy to underestimate, particularly when projects move from demonstration to production. Executives can improve control by funding AI in stages, with clear limits and decision points. Require each project to define expected usage, business value, accuracy needs, and total operating cost. Track spending by team and use case, set alerts and quotas, and review actual costs monthly. Negotiate vendor protections, avoid unnecessary dependence on one provider, and maintain contingency budgets for rapid growth, compliance changes, or unexpected technical work.

AI spending is difficult to forecast because costs depend on both technical choices and how employees and customers actually use the technology. An application that succeeds can become more expensive quickly: every additional question, document, or automated task may generate a charge, and long or complex requests often cost more. Prices and demand also change. Providers revise fees, introduce new models, and offer discounts with different conditions, while scarce computing capacity can push up infrastructure costs. Meanwhile, spending extends beyond vendor bills: preparing data, integrating systems, checking accuracy, protecting sensitive information, and meeting regulatory obligations all require people and money. To gain control, set a budget for each use case and assign an accountable owner. Track the full cost per useful outcome, such as a resolved customer enquiry, rather than simply counting subscriptions. Start with limited pilots, measure savings and quality, and expand only when the results justify the expense. Use spending alerts and limits, and review supplier contracts for pricing changes and exit costs. Choose less expensive models for routine tasks, reserve premium options for demanding work, and reduce unnecessary requests. Finally, forecast a range of scenarios rather than a single number, including rapid adoption and unexpected compliance costs, and revisit those forecasts regularly.
